ROY BLACK, OF CLEVELAND, OHIO.

LOADER.

Application led January 3, 1820. Serial No. 349,228.

To all whom 'it' f/naly/ concern.'

Be. it known that I, Rox BLACK, a citizen of the United States, resident ot' Cleveland, county ot Cuyahoga, and State of Ohio, have invented new and useful lmprovements in Loaders, of which the following is a specification, the principle of the invention bcing heroin explained and the best mode in which l have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to loaders, and particularly to devices or this character adapted to be used with a seit-propelled vehicle such as a tractor.

The annexed drawings and the following description set Jforth in detail certain means embodying my invention, the disclosed means, however. constituting but one of the various mechanical forms in which the principle of the invention may be employed.

In said annexed drawings:

Fig. 1 represents a side elevation partly in section.

Figure 2 represents a plan view of my improved loading` mechanism and tragmentary portions of the front end ot the tractor to which the same is connected; and

Figure 8 represents a transverse vertical section` taken on the plane indicated by the line Ill-1V, Figure 2.

ln said annexed drawings, a standard tractor design is indicated bv the ordinal 1, having the longitudinal side channels 1. My invention contemplates the pivoting of a scoop to the iront end of said tractor 1 so that the scoop may be. forced into dirt, gravel or other material which it is desired to load or to move from one position to the other. rthe scoop 2 is provided with a bail 3 and is formed with longitudinal strengthening channels 2 disposed adjacently its upper edge.

rlhe scoop 2 is connected to the tractor 1 bv means of bars 5 secured to the front ends ol the channels 1 and having forward downwardly members 5 riveted to a pair` of upwardly extending channels 7. A rod G extends through both members 5 and the channels 7 and upon this rod the scoop is pivoted.

The upwardly extending channels 7 are spaced from the scoop channels 2 and two sections ot pipe 27 surrounding the rod 6 are utilized as seperators and strengthening members between the channels 2 and 7.

rllhe upper ends oic the channels V7 are spaced and strengthened by the transversely extending member '8. The channels 7 are further braced by means of the arms 9 connected at their lower ends intermediately of the ends of the channels 1 and at their upper ends to the channels 7 at the points 10 intermediately olf the upper and lower ends of the latter.

l provide means for raising and lowering the scoop` 2 or 'for holding the same at any desired elevated position. kTo this end a cable 11 is secured to one end ot the bail 3 and passes over a roller 12 mounted adjacently to the upper ends of the channels i and between said channels, as 'plainly shown in Figure 1. rlhe crank-shaft of the tractor is indicated by the ordinal 13 and a clutch member let .isV secured thereto. A second clutch member 15 is tixedly secured to a. frame member 16 of the tractor and in axial line with the clutch member let. Two movable clutch members 17 and 18 adapted to cooperate respectively with the clutch members .1st and 15 are formed integral with or secured to a drum or shell 19 loosely mounted upon the crank-shaft 13. The clutch member 18 is formed with a collar 18 disposed intermediately the ends of its beveled face, as plainly shown in Figures 1 and 3. The other end of the cable 11 is secured to the drum 19 and the cable is adapted tobe wound upon said drum intermediately of the clutch members 17 and 18, the collar 18 preventing the adjacent section of the cable 11 from interfering with the action ot the clutch members 15 and 18. ln order to act-nate the movable clutch members 17 and 18, I provide an upwardly extending bar 2O pivot-ed adjacent its lower end to the front ot the tractor 1 andv pivotally secured at its upper end to a longitudinally extending bar 22. This bar 2O is secured by means of a pin 20 to one sideface of 'the collar portion 18 of the clutch element 18 and is also secured by means et an angular extension 21 to the diametrically opposite face of said collar member 18. The bar 22 is formed adjacent its'rear end and upon its bottom' face with a series of notches 23, and a. grip 24. An upwardly extending bar secured to the rear ot the tractor 1 is formed with a slotted head member 2G having a tooth portion co-'operating with the notches so as to loc-li the arm 22 in any desired longitudinal position,

Within the range allowed by the notches 23. lt is evident that it the crank-shaft 13 is rotated counter-clockwise, a backward pull upon the grip 24C vvill throw the clutch element 17 into engagement With the clutch element lil and result in the lifting of the scoop 2. lt is also evident that it the bar 22 is forced forwardly, this action will result in the engagement ot' the clutch element i8 with the clutch element l5, resulting in a. holding of the scoop 2 in a desired elerated position. Then both pairs ot' the eo-operatingrlutch members are released, the scoop t2 will `fall by gravity.

.is an illustration et' the Working ot' my improved loader, we will assume that the tractor l is driven up to a pile ot' `gravel with the scoop 2 elevated to clear the surface of the ground. lVhen the gravel pile is reached, the scoop 2 is lowered or elerated, as is necessary to properly dig into the pile, and the tractor driven forward so that the scoop penetrates the pile and is properly fille-d. Then the clutch elements let and 17 are brought into engagement and the scoop 2 elevated somewhat higher than the position neressary to clear the ground and to hold its contents. Then the clutch elements l5 and 18 are brought into engagement, any slight dropping' of the scoop 2 during the time ot passage of the clutch elements through neutral position being compensated for \y the fact that the scoop 2 had heen elevated somewhat above the required po sit-ion. The tractor is then backed oil and run up onto the dumping or loading;` platform, whichever disposition it is desired to make of the scoop contents, and the clutch elements l5 and 18 released so as to allow the scoop to tall by gravity, when the contents will run out by gravity or can be easily pushed. or pulled out by suitable tools. The scoop is then again elevated `an amount necessary 'o clear the surface of the ground, fixed in this position and the tractor driven up adjacently to the gravel pile.

lli/What l claim is:

l. A tractor loader of the character described comprising a. crank-shaft, a clutch element lixedly secr-.red to the crank-shaft beyond the front of the tractor, a second Clutch element fixed to the upright front end ot the tractor, a sleeve mounted upon said crank-shaft intermediate said clutch elements and termed with a. pair ot co-operatingg clutch elements, and means 'for moving` said sleeve so as to engage or release the clutch elements.

2. A tractor loader opt the character described comprising a crank-shaft, aclutch element Xedly secured to the crank-shaft beyond the front @t the tractor', a second clutch element fixed to the upright front end of the tractor, a sleeve loosely mounted upon said crankshaft, and formed with a pair ot' cri-operating clutch elements, one oi said clutch elements being formed with a collar disposed intermediately the ends of its beveled tace, said collar extending beyond the periphery of said clutch members, and means for moving' said sleeve so as to engage or release the clutch elements.

Signed by me, this 29th day ot December, 1919.
